+### Captures are local-only (issue #49)
+
+The repository carries **code, tooling and docs**. Screenshots and savegame
+blobs are game-derived, so since 2026-09-19 they live in `docs/re/captures/`
+on disk and are **gitignored** — the pages' relative links still resolve on a
+machine that has them, and nothing ships.
+
+Derived measurements (`csv`, `tsv`, `txt`, `log`, `json`, `jsonl`, `npy`) are
+our own numbers rather than game content, and stay tracked — they are what most
+claims here actually rest on.
+
+`tools/re/check-capture-citations` enforces both halves: a cited capture must be
+**present**, and a game asset must **not be tracked**. ⚠️ A fresh clone has no
+captures, so its citations will not resolve until the captures are copied in;
+that is expected, and the checker is a local gate rather than a CI one.
